Charlie saves $90.
Bryan saves 3 times as much money as Charlie.
- How much does Bryan save?
- How much does Bryan save more than Charlie?
- How much does Charlie save less than Bryan?
- How much do both of them save altogether?
(a)
Focus on the sentence with the word 'times'.
Assign 1 u to the variable that is found after the word 'times'.
Amount that Charlie saves = 1 u
Amount that Bryan saves = 3 u
1 u = 90
Amount that Bryan saves
= 3 u
= 3 x 90
= $270
(b)
Amount that Bryan saves more than Charlie
= 3 u - 1 u
= 2 u
= 2 x 90
= $180
(c)
Amount that Charlie saves less than Bryan
= 3 u - 1 u
= 2 u
= 2 x 90
= $180
(d)
Total amount that both of them save altogether
= 1 u + 3 u
= 4 u
= 4 x 90
= $360
Answer(s): (a) $270; (b) $180; (c) $180; (d) $360
